Two things here:
1) The vircurex staff is quite slow when it comes to performing actions. For example, the whole wallet service was down for a month until it was noticed (maybe staff was on holiday). However, they DO work on things, it's just that it feels like they are not responding to mails. Have you got any response from them lately?
2) How would it in practice work to switch to a newer wallet? Assuming vircurex would not update their wallet, is the only option to withdraw to an OWN wallet of the older version (probably downloadable somewhere) and then update that one? What about Cryptopia now, if they add TRC, I presume it'll be the old wallet(?) - if that's the case, then withdrawing from vircurex straight to Cryptipia while they are still on the old wallet would be the easiest solution, right? And lastly, why would any coins be lost in the process as you could at any point use the old own wallet to withdraw to and update it if needed? I'm a bit confused about these things
1. I haven't gotten a response. I think Vircurex may just be one dude which is why they are so slow to respond to change. Once the new wallet is in the testing phase then I will create a new community task to have everyone email and warn Vircurex to update the wallet. I think with enough emails they will be made aware. I would recommend removing all of your TRC to a local wallet before that time. It is really in Vircurex's best interest to update the wallet, so I don't think they will willingly not update their wallet.
2. The old wallet is linked to in this OP. To switch to a new wallet you should just be able to download the new wallet client and replace it. Always back up your wallet.dat file first. I actually back up my wallet.dat file (renamed) to a cloud backup service as well. I am going to update the poll today or tomorrow to ask the question about adding to Cryptopia. We have around 3 million DOT donated to get us added to Cryptopia but it might be better to wait until we have the new wallet. I sent Cryptopia a support request asking if we should wait, and if we could get in on their 500k Cryptsy crash cheaper add. I have not heard back yet, but if they agree I will sell the left over 2.5 million DOT that has been donated and buy TRC to be added to the logo bounty.
You should not lose any coins by updating the wallet (when it happens). You only could lose coins by staying with the old wallet. Since everything is peer to peer once 51% of the people have switched to the new wallet your old wallet just won't work so all of the coins in there will not be accepted by other wallets until you update it. I am not sure if I answered your questions. Tell me what I missed.
